Hi, since owning my horse for almost 2 month who's on working livery he's been on hay and a small daily feed of pony nuts and HiFi, he's also out on grass. The yard he's on has changed to haylage and our horse has gone totally crazy. He has dumped my daughter in sand school was galloping & bucking and had a completely wild look about him, he also tried to bite me. Since owning him we've never had any bad behaviour and before buying him my daughter was riding him for a round 5 mths at the riding school, could it b the change to haylage and if so should I put him back on hay? Also if he goes back on hay should he have it dry or wet? He's always had it dry before but reading on other sites people saying it should be wet?!
